Stellar chromospheric activities revealed from the LAMOST-K2 time-domain survey

Henggeng Han, Song Wang, Yu Bai +3

By using the LAMOST time-domain survey data, we study stellar activities based on the lines for about 2000 stars in four 2 plates. Two indices, and…

A dynamically discovered and characterized non-accreting neutron star -- M dwarf binary candidate

Tuan Yi, Wei-Min Gu, Zhi-Xiang Zhang +26

Optical time-domain surveys can unveil and characterize exciting but less-explored non-accreting and/or non-beaming neutron stars (NS) in binaries. Here we report the discovery of…

LTD064402+245919: A Subgiant with a 1-3 M Undetected Companion Identified from LAMOST-TD Data

Fan Yang, Bo Zhang, Richard J. Long +11

Single-line spectroscopic binaries recently contribute to the stellar-mass black hole discovery, independently of the X-ray transient method. We report the identification of a sing…

A Catalog of Short Period Spectroscopic and Eclipsing Binaries Identified from the LAMOST & PTF Surveys

Fan Yang, Richard J. Long, Su-Su Shan +7

Binaries play key roles in determining stellar parameters and exploring stellar evolution models. We build a catalog of 88 eclipsing binaries with spectroscopic information, taking…
